Özet

Lignite was extraced with water and with water-tetralin-mixtures in sub- and supercritical states. With the help of the technique used, it was possible to study the mechanism of decomposition of the lignite during the extraction. A simple reaction-kinetic model was used to obtain the activation energy and the frequency factor for the extraction with water, respectively water-tetralin-mixtures. A process for upgrading of lignite with water, respectively water-tetralin-mixtures was proposed.
